摘　　要：以偶氮二异丁睛(AIBN)为引发剂,选择甲基丙烯酸丁酯、丙烯酸和丙烯酸丁酯等单体共聚,合成丙烯酸酯树脂;选择-苯基三乙氧基硅烷与二甲基二乙氧基硅烷为单体进行水解缩聚,合成有机硅树脂低聚体;通过有机硅树脂低聚体与丙烯酸酯树脂的接枝反应,合成有机硅低聚体改性丙烯酸酯树脂,并对影响改性树脂性能的重要因素进行了探讨,找出了合成改性树脂的最优条件。In this paper,siloxane-acrylate resin was obtained by the branch reaction of acrylate resin and siloxane-oligomer. Acrylate resin was synthesized by the polymerization of MBA,AA and BA with AIBN as, initiator, siloxane-oligomer was prepared by the hydrolysis and polycondensation reaction of phenyhriethoxysilane and dimethyldiethoxylsilane.The important factors for influence on properties of siloxane-acrylate resin were discussed ,the optimal formulas for resin were obtained.
